CTA guides thousands of commuters daily thanks to indoor and outdoor signage printed using HP Latex Printing Technologies


"HP allowed us to produce
the signs with a turnaround
time that we could not have
achieved before. We counted
on its reliability and versatility
to complete the job on time."

— Victor Ramirez,

  • CTA needed to print directional signage indicating alternative transportation in 36 hours, in time for Red Line shutdown, affecting 54 stations in Chicago.
  • It had to create resistant and durable indoor and outdoor signage for a wide range of applications.
  • It also wanted to reduce the impact of printing on the environment and eliminate harmful gases from the work environment.


  • CTA selected fast-drying HP Latex Inks with the HP Latex printer to create indoor and outdoor signage, in combination with HP Permanent Gloss Adhesive Vinyl for sandwich boards at shuttle bus stops; HP Premium Vivid Color Backlit film for illuminated maps; and HP Dupont Tyvek and HP Latex Durable Frontlit Scrim Banner for construction boards outside stations.


  • CTA printed and finished 1,350 ft2 (411.48 m2) of signage in 36 hours - ready for weekend installation to meet critical Monday deadline.
  • It achieved 30 percent faster production of high-quality signs, with accelerated finishing thanks to fast-drying HP Latex Inks.
  • Simplified work processes helped to reduce the overall impact of printing compared to eco-solvent ink printing processes with the use of water-based HP Latex Inks, which require no special ventilation in the work environment.
